Recently, China Mobile, working hand - in - hand with manufacturers such as FiberHome, has accomplished the inaugural 800G live network pilot in Sichuan Province. In the context of English expression habits, using "teams up with" instead of "in collaboration with" can make the tone more lively and natural. This pilot was specifically designed for key scenarios in data center interconnection. Its primary objective was to significantly boost transmission speeds and expand network capacity. From a cultural background perspective, in the tech - related field, clear and straightforward goals are highly valued. The project successfully set up an OTN (Optical Transport Network) transmission system that spanned across four core computing nodes. Moreover, it carried out live network verification of 800G transmission, leveraging 130G baud rate technology. This effort is geared towards accelerating the practical implementation of high - speed transmission network technologies.
